Several Ways To Record With Less Noise


Of course, you shouldn’t exclusively rely on noise reduction plugins for clean mixes.  

Instead, you should try a few things to reduce noise while recording, including:



  • Reducing the subject-to-microphone distance
  • Eliminating background noise sources
  • Using directional microphones
  • Using a low-cut filter on the microphone 
  • Using a real-time noise suppression unit


If you notice that your audio is still suffering from noise after these things, then you can use one of these handy noise reduction plugins.

Of course, you may need a great set of headphones to actually perceive the noise, which is why I'd recommend checking out a pair of either Sennheiser HD 650s or HD 660S2s.

Sonnox Restore Bundle


The Sonnox Restore Bundle comes with the Sonnonx Oxford DeNoiser, which is one of the best plugins for surgical noise reduction. It’s one of the most versatile noise suppressors out there, using five noise reduction modules and a spectrum analyzer to monitor how the plugin is impacting your audio. 

All of the parameters on this plugin can be modified and bypassed without turning the plugin off. 



We absolutely love the De-hisser parameter, which you can use to reduce the level of hiss noise and high frequencies without impacting the rest of the signal. This function is very beneficial if you have noisy analog equipment or use cheap microphones for recording.

The intuitive controls of the Sonnox Restore plugins makes them a delight to work with and one the high quality of Sonnox plugins make them some of the best noise reduction VSTs out there.



Acon Digital Restoration Suite


While the entire Acon Digital Restoration Suite is top-notch, the true hero in the noise reduction realm is Dialogue. This fully automatic noise reduction plugin is made exclusively for the voice. The real-time algorithm suppresses background noise in real-time, making it ideal for singers, interviews, and podcasts.

The algorithm on the plugin was trained with vocal samples so that it can distinguish the timbre, behavior, and frequencies found in different human voices.

However, if the automation isn’t quite cutting it, you can take advantage of the three-band onboard EQ to increase or decrease noise reduction applied to various portions of your incoming signal. This level of flexibility is what makes the Acon Digital Restoration Suite so useful!


Most Affordable Noise Reduction Plugin - Waves NS1


The Waves NS1 noise reduction plugin was designed with simplicity in mind. However, though it may not look like much, the results that you can get out of this thing are pretty incredible. 

You’ll often find that most people using the NS1 plugin work in the video editing world. 




The beauty of the NS1 is that it is super easy to use. All you have to do is pull the slider down until it begins reacting to your audio. Then, the plugin will apply adaptive noise reduction to your audio.  

Sometimes, you need a plugin without all of the bells and whistles that can work in a pinch. Waves NS1 is just that!

MCDsp NR800


The NR800 noise reduction suppressor from MCDsp is a real-time solution for music production, post-production, live sound, and just about anything else! However, where it truly excels is with dialogue. It’s wonderful for cleaning up audio contamination from microphone bleed or field recordings. 



Even in aggressive settings, you’ll never notice any strange, unwanted artifacts. With just a few clicks, you can get rid of windy rumble or hissing noise. 

We love that the McDSP NR800's per band controls really enable you to isolate troublesome noises without mutilating your overall track.


Waves Z-Noise


Z-Noise is another noise reduction plugin under the Waves banner, which boasts a unique algorithm that eliminates noise from background recordings without compromising the quality of the audio or inducing artifacts.

With Z-Noise, you can specify the noise print that you are targeting and want to get rid of. The plugin will then hone in on those offending frequencies. How much it hones in on the frequencies depends on how much you pull down the threshold. 



One of the plugin’s biggest strengths is certainly the absence of smearing, which is why it has become a go-to choice for many. However, Z-Noise isn't as strong as an all around noise reduction plugin as some of the others on this list. Its core strength is reducing hiss from poorly shielded guitars and amps.

So if your recordings are to hissy and you don't have a lot of money to spend, check out Z-Noise.


MCDsp NF575


Another offering from MCDsp is the NF575 noise filter. This high-resolution filter can remove a number of noise types from audio thanks to the accurate high and low-pass filters with selectable slopes. 




Onboard, you’ll find advanced notch filters that you can use to select the amount of signal you want to reduce. You can link all five of these filters to address common noise problems, such as 60Hz hum. With an extremely narrow, linkable design, you can remove the cyclical or harmonic noise without impacting the good parts of your audio. 


Best Waves Noise Reduction Plugin for Vocal Waves Clarity VX


Waves just recently came out with the Clarity VX and it is absolutely astounding. 

The plugin offers one of the most efficient ways to clean your vocal recordings and rid them of hiss, hum, or harshness. Waves Clarity VX uses the new Waves Neural Network engine to impeccably clean vocals without any damage to the performance. 




Without a learning curve, you can do it in seconds. The fact that back in the day, cleaning vocals like this would require serious engineering ingenuity, and now it only takes a few seconds, is quite amazing. 

If you’re looking for the best plugin on the market to provide real-time noise reduction on your vocals, this plugin is it. 

However, as amazing and affordable and recommended as Clarity VX, it does not work well on instruments, so you'll still need some other plugins if your other sounds also have noise!


Best Noise Reduction Plugin for Podcasters: IDC Instant Dialogue Cleaner


We’ve been enjoying the large knob-style plugins that have been coming out on the market lately, and IDC Instant Dialogue Cleaner is a prime example. Even with its simple interface, it offers some of the best noise reduction capabilities on the market. 

If you're a podcaster looking for an affordable, easy to use plugin to clean up your podcast, this is what we'd recommend. The fact that you don't need to be an audio engineer to get great results is why we think this is the best noise reduction VST for podcasters.

Its quality of noise reduction is all thanks to its deep neural network, which separates noise from speech to preserve what should remain and get rid of what isn’t wanted. From traffic noise to room ambiance to nature sounds and beyond, all you have to do is twist the knob to hear the best version of your audio come to life.

Best Free Noise Reduction Plugin - Voxengo Redunoise


Voxengo Redunoise is one of the latest offerings from Voxengo. While it may look a bit outdated, it is a quality broadband noise reducer that can work for all kinds of noisy program material. 

You’ll find standard noise reduction controls, including Threshold, Reduction, Attack, and Release. However, one of the things we really love about Voxengo Redunoise is that the developers added a Mix knob, allowing you to process the noise out of your audio in parallel.  

I highly recommend trying this plugin out if you can, as it’s completely free to test out! 

From a Frustrated Producer in a Ragtag Bedroom Studio to Major Placements on TV Earning $1,000s!


My name is Evan, and I've been making music since around 3rd grade. I'm from San Diego, California, but I've lived in Washington, DC for the last 20 years.

After 3 grueling years of grad school, though I had put aside serious attempts at making music. I found myself spending my days doing work that was dreadfully uncreative, with a ton of student student loan debt.
Which made me feel like my favorite parts of myself were withering.
But I didn't know what to do about it.
Being in my early 30s with tons of student loan debt, in a world where there is "no money in music," I felt like my youthful dreams of trying to "make it big" were dead. Like my music would remain unheard in my head and hard drive. 
Frustrated by my inability to get my music heard, I started researching solutions.
Instead, I wanted to find a way where I could focus on making the music and let someone else deal with promoting it. 
I realized the music licensing was the perfect opportunity for a solo artist like me to get my music heard, without having to do any promotion. I just need to focus on improving what I could control - my songwriting and my production skills.

While I still have a full-time day job, I have created systems that have allowed me to produce dozens of songs a year in my spare time.

My¬†songs have been on Netflix, TV shows like the 90 Day Fiance, an award-winning indie film, and NPR‚Äôs ‚ÄúAll Thing Considered.‚ÄĚ They've also been streamed millions of times.

In addition to being a music producer, I am passionate about teaching people how they can make professional-sounding music and earn money licensing it, all in their spare time.

Thousands of musicians, like yourself, have trusted me to guide their musical journey. My YouTube videos have been watched nearly a million times. And my story has been in Forbes, Side Hustle Nation, and the Side Hustle School.
